摘　　要：β-葡聚糖(β-glucan)作为一种免疫刺激剂,表现出广泛的免疫学生物活性。有关研究表明,β-葡聚糖能够促进鱼虾的生长,提高抗氧化酶活性、有效清除体内的自由基,增强免疫相关酶活性、促进免疫球蛋白的合成、激活补体系统及产生杀菌物质提高动物的免疫力,提高某些免疫相关酶基因的表达水平,增强动物的抗感染能力,是目前水产养殖中研究最为深入、应用广泛的一种免疫刺激剂,对集约化规模化养殖条件下提高动物的抗氧化应激和免疫能力具有良好的作用,展现出广阔的应用前景和价值。对β-葡聚糖提高水产动物生长性能、抗氧化和免疫能力及抗感染水平等方面的研究进展进行综述。β--glucan （βG） as one type of immune stimulants shows a wide range of immunological bio-activities. Studies in aquatic animals showed that β-gluean could promote the growth performance of fish and shrimp and activities of antioxidant enzymes, effectively remove free radicals within the body, enhance the activities of immune-related enzymes, promote the synthesis of immunoglobulin, and activate the complement system and antiseptic matters to improve animals imnmnity. Moreover, it could improve the gene expression level of certain immune-related enzymes and enhance the capacity of animals＇ resistance to infection. So far, β-glucan is the immune stimulant most in-depth researched and widely used in aquaculture, which improves animals resistance to oxidative stress and immunity in intensive and large-scale culture, and shows a wide range of application prospects and values. In this article, the effects of β-glucan on growth performance, oxidation resistance, immunity function and anti-infection were summarized.
